Norovirus is a very contagious virus that can infect anyone. You can get it from an infected person, contaminated food or water, or by touching contaminated surfaces. The virus causes your stomach or intestines or both to get inflamed. This leads you to have stomach pain, nausea, and diarrhea and to throw up. These symptoms can be serious for some people, especially young children and older adults...

First Ever - Human norovirus successfully grown in a lab!

CDC celebrates the work of scientists at Baylor College of Medicine in Texas, who recently developed a way to grow human norovirus in cells that line the human intestine. This is a major scientific achievement that has been more than 40 years in the making after numerous attempts by many labs, ever since norovirus was first discovered. This discovery will help us better understand basic human norovirus biology, and how to prevent and treat norovirus infections, the most common cause of diarrhea and vomiting in the United States and globally.

Norovirus Collection

This PLOS norovirus collection fills critical knowledge gaps and provides key information for the development of a much-needed vaccine. This is a "living collection" and more articles will be added over time.

Norovirus Outbreaks

Norovirus outbreaks occur throughout the year. But, over 80% of the outbreaks occur from November to April. Learn more about U.S. Trends and Outbreaks.
